Specification of Letters Patent.

Application filed May 2, 1907. Serial No. 371,416.

To all whom it may concern:

Be it known that I, JAMns A. KEYEs, a citizen of the United States, and resident of the city, county, and State of New York, have made certain new and useful Inventions Relating to Soap-Presses, of which the following is a specification, taken in connection with the accompanying drawings, which form part of the same.

This invention relates to presses and relates especially to presses adapted for forming cakes of soap or other articles and im pressing designating marks therein, feeding devices being provided to properly feed the articles to and from the dies and to maintain them in alinement.

In the accompanying drawings showing an illustrative embodiment of this invention, Figure 1 is a plan view. Fig. 2 is a vertical section along the line 2-2 of Fig. 1. Fig. 3 is a similar section along the line 3-3. Fig. 4 is a vertical section along the line 44. Fig. 5 is a partial section showing the slide and die. Fig. 6 is a similar partial view showing the parts in different osition to illustrate the feeding of the artic es. Fig. 7 is a partial plan view for this purpose.

In the illustrative embodiment of this invention shown in the drawings, a rigid frame is formed by the supports 1, 2 which are firmly braced together by the transverse members 16. Suitable bearings 5, 6 are provided in this frame for the drive shaft 4 which may have the drive pulley 8, if desired, to operate the machine. The die cams 7, 8, may be mounted on this shaft 4 as well as the supply pinion 47 meshing with the gear 46 on the stub shaft 45 so as to operate the sprocket chain 44 and rotate at the desired speed the sprocket wheel 43 connected to the supply drum 35 shown in Fig. 3. In this way the supply belt 68 is operated at the desired speed, the belt passing over the idle pulley 36 indicated and feeding a series of articles forward between the guides 34, 37 shown in Fig. 1, so that the foremost of these articles engages the aliner 87 which may be arranged transversely across the path of these articles, the guide 37 being preferably adjustably mounted by the slotted ears 38.

The cam shaft 12 may be mounted in suitable bearings 11 secured to the frame and driven from the drive shaft by the bevel gears 9, 10, this shaft preferably carrying 15 to operate the feeder. The feeder 23 may be mounted in a suitable bearing 39 adjacent one end of the table 66 and in the bearings 26 which may have the construction shown in Fig. 4. In that figure a bushing 28 is shown as engaging these bearings and held in longitudinal alinement therewith by the collar 27 secured to the bushing in any desired way. This bushing preferably has a non-circular hole extending therethrough with which the correspondingly shaped end 24 of the feeder engages so as to freely reciprocate in the bushing, but be held against relative rotation with respect thereto. ing and is provided with a suitable follower 71 engaging a suitable groove in the oscillating cam 15, so that as this cam rotates the arm and the connected bushing and feeder are correspondingly oscillated.

The reciprocating cam 18 is provided with a cam groove engaged by a suitable roll on the lever 14 which as indicated in Fig. 4 may be mounted on the pivot 88 and pivotally connected at its upper end with the link 30 pivoted to the collar 29 on the feeder so that hi this way the feeder is longitudinally reciprocated to the desired extent at the same time that it is oscillated by the mechanism described.

The slides 18, 19, are preferably mounted in suitable grooves in the ways 17 so as to be accurately guided in their movement, the slide 18 being provided as indicated in Fig. 2 with the head 22 to which the rear die 69 is secured in any desired way. The slide 19 is shown as provided with a similar head 21 to which the front die 64 may be secured. The slide 19 is reciprocated by the follower 48 secured to the lug 63 in the slide and having the roll 89 secured thereto and cooperating with a cam groove in the die cam 8. The slide 18 has a similar lug 62 to which the follower 49 may be pivotally connected, the roll 50 on this follower engaging the cam groove in the cam 7, the follower being preferably guided by having a yoked end on either side of the guide block 61 supported by the drive shaft 4, as seen in Fig. 2.

If desired, a suitable recess may be formed in the cam groove 60 so that when the final compression movement of the dies takes lace the rear die is not positively operated by the roll which has considerable back-lash the feeding cam 13 and oscillating cam in this part of the cam groove 60, the die be- The arm is secured to this bushing yieldingly supported so as to prevent eX- cessive pressure on the article within the die casing 20. This yielding action may be effected by a suitable spring buffer mounted on the frame and co6perating with a lug 55 on the slide, this buffer preferably comprising the head 56 engaged by the spring 57 and having its stem 53 passing through the adjustable sleeve 89 which may have threaded engagement with the yoke 51. Suitable nuts 52 may be used on the stem to prevent the excessive outward movement of the head.

The row of articles, such as cakes of soap 72, may be supplied to the belt 68 and fed along the same between the guides until the foremost cake is brought into engagement with the aliner 87. Thereupon further for Ward movement is prevented and the supply belt may under these conditions slip beneath the articles. The feeder is thereupon oscillated into its inactive position so that its blades 58, 67, on the arms 31, 32, are withdrawn from the path of the articles on the table 66 and moved into the raised position indicated in Fig. 4. Thereupon the feeding cam and connections reciprocate this feeder into its rearward position, where the blades are brought on either side of the article 72 in engagement with the guide 37 At this time the oscillating cam and arm operate and the feeder blades are swung downward on either side of this article, as indicated in Fig. 6, the detacher 77 thereupon engaging the article which. has just been acted upon by the dies and forced out from the die casing 20 as the front die recedes into the position indicated in Fig. 7. This detacher may be yieldingly connected with the feeder by having its stem 74 pass loosely through an opening in the guides 75 secured to the extension 33 of arm 31, a suitable spring 76 being provided within this guide to normally hold the detacher downward with the desired force. The engagement of this spring detacher with the article effectually disengages it from the rear die and forces it down slightly so that it engages with the table 66. Thereupon the feeder is reciprocated in a forward direction carrying the article 72 forward along the table into alinement with the die casing and dies, also moving the preceding articles along the table. In this way each article is accurately fed forward by the feeder and alined with respect to the dies, the forward movement of the feeder taking place while its blades are oscillated into their lower position so as to engage the articles while its rearward reciprocation takes place while the feeder has been raised out of the path of the articles. After moving along the table 66 the comleted articles may pass upon the discharge tielt 72 operated by a suitable pulley 73 on the cam shaft by which they-may be conveyed to. anydesired receiving or packing mechanism.
